The most important population movements are the international migrations, the impact within culture, the economic development, social changes and ways of thinking. This happened in the Caribbean islands and Latin-American, widely marked for the Spanish and other European countries immigration. European migration to America is not a recent phenomenon. Always have there been migrations, but on a worldwide level never was so numerous and with such different characteristics like this one. In some cases it has become socioeconomic and cultural problem, in the receptive countries, like sometimes with the Spanish emigration to Latin-America.Its interesting to know the multiple causes of the Spanish exterior emigration (economics, social, politics…), for that we need to analyse the relations between the living conditions in the origin and arrival areas.
